Just cleaning up shop, as they say.  Had these gauges in plastic bags on a shelf for years.  I have no idea what works and what doesn't, or if either does work.  The wiring harness, illumination bulbs and holders, came from a 914 gauge, I pretty sure, but I don't know if it was one of these gauges or not.

Gauges are part #s:

914.641.102.20 and 914.641.102.10.

Being sold as a lot for parts - I'm sure they'll be useful to someone.
